As you can see, many of the biggest names in American retail are still missing from the list, including the nation’s largest supermarket operator, Kroger, which owns such chains as Ralphs, Fred Meyer, Smiths, Harris Teeter, and King Sooper’s. All of the dollar store operators; Walmart, the largest retailer in the universe; Amazon.com; most department stores; and all of the hardware and home improvement stores are also missing.
